Abstract

0.33-33% of the Cu in superconducting YBa2Cu3Oy has been replaced by Li (i.e., x=0.01-1 in single-phase or nominal YBa2Cu3-xLixOy). X-ray diffraction powder patterns remain the same as for YBn2Cu3Oy, with identical patterns up to about 17% substitution (i.e., x=0.5). At higher percentages an additional phase appears. Electrical conductivity measurements indicate a small elevation of Tcat low Li content. Starting at about 5% Li (x=0.15), Tcdeclines progressively and its width increases as x is raised. © 1989 Plenum Publishing Corporation.
